Along I-40 west of Amarillo.
Here is one I found pretty quickly on street view. I don't know how many of them there are that are paved vs. the ones that are not, I could have missed some as I was going through at night when I actually pulled over my car on the shoulder to verify I saw what I thought I saw, and realized Texas actually has at grade intersections on a supposed interstate. I am not sure if they only do this on this section of I-40 or not, but it is a bad practice none the less because it sets a bad precedent, imo.
I'm going to eventually send a letter via email to the FHWA and TxDOT about this and see what their take on this is and I'm interested in hearing TxDOT's defense of building these. I have never seen this anywhere but West Texas on I-40.
